The plasma membrane of a photosynthetic eukaryotic cell
A) converts carbon dioxide and water into sugars.
B) isolates the cell's contents from the external environment.
C) controls protein synthesis in the cell.
D) is composed of cellulose.

Question

Quizplus · Accepted Answer

The plasma membrane is the outermost layer of the cell that separates the cell's contents from the external environment. It plays a crucial role in maintaining the integrity of the cell by regulating the movement of substances in and out of the cell. While photosynthesis occurs within the chloroplasts of a eukaryotic cell, the plasma membrane is not directly involved in the conversion of carbon dioxide and water into sugars. Protein synthesis is controlled by the ribosomes and endoplasmic reticulum within the cell, and cellulose is a component of the cell wall in plants, not the plasma membrane.
